TO ALL WHOM IT MAY CONCERN;

Be it known that I, JACOB D. SPANG, of Dayton, in the county ofMontgomery, and State of Ohio, have invented a new and improved GasolineHeating Apparatus; and I do hereby declare the following to be a. full,clear, and exact'dcscription of the same, reference being had to the.accompanying drawings, forming part of this specification, and in whichFigure 1 is a vertical section of my invention.

Figure 2 is a top view of the burner C.

Similar letters of reference indicate corresponding partsin the twofigures.

. In this invention a new form of gasoline burner is used, and a newdevice is employed for utilizing the heattof such burners, andconcentrating it upon particular points where the apparatus to be heatedis situated.

In order that others skilled in the art to which my invention appertainsmay be enabled to make and use the same, I will proceed to describe itin detail.

In the drawings, A represents a reservoir, filled with gasoline, andcommunicating by the pipe B B with the burner C.- Thelower extremity ofthe pipe B, it will be observed, is bent in the form of a square, havingthe burner in the centre of its lower side. Its upper extremity isprovided with a st'op-c0ck, b, to regulate the flow of oil from thereservoir. Around the burner and lower part of the tube B is a screen,D, of sheet metal, in shape the frustum of a cone, and having clustersof perforations d d at diflerent points in its walls. The top of thisscreen'is fitted closely around the tube B, and the whole screen forms achamber, in which all the heat of the burner is collected, and fromwhich the heat and heated air, gases, &c., are delivered only throughthe perforations d d (1. Outside of this again is another chamber, E, ofsheet metal, of the same form as the screen D, but larger in all itsdimensions. -In the walls of this chamber, at e e c, extending inwardopposite to the perforations cl d d, are small compartments or heaters,into which access can be had only from the outside. They are ofdifferent shapes, to receive smoothing irons, or whatever else it may bedesired to heat in them, and are so arranged, with reference to theheat-discharging perforations cl d d, that all the heatpossible shall beutilized upon them. Covers F are provided, which can be adjusted inposition, as shown in the drawings, and when the smoothing-irons, &c.,are being heated, will confine the heat in the compartments e e c.

This whole apparatus is placed upon a stand, consisting of a perforatedplate,- G, supported upon legs H H H, and is firmly attached to it bymetallic rods I I I, extending from the top of the chamber E to theplate G, and confined by nuts and screws, or in other suitable manner..A valve is provided in the walls of the chamber E at K. W

The burner C, it will be observed, is of peculiar construction, being ahexahedron, with top slightly smaller than bottom, and having two slitsc c in its top, crossing each other at right angles in the centre of theburner, where there is stationed a small button, 9:, for the purpose ofthrowing the flame from the centre. The square portion of the pipe B isattached to the upper part of the pipeby a screw-joint, z. Asbestosmaybe placed inside of the pipe B B, if desired, through which the oilwill filter, and which will thus regulate the supply of oil to theburner.

A great advantage is derived from the form and position of the squareportion B of the pipe, as it enables the heat of the lamp to becommunicated to the gasoline-just at the point where it is necessary toheat it in order to volatilize'it and bring it to the burner in thecondition of gas. The form and construction of burner shown anddescribed'will also be found to.possess advantages over those hithertoin use, being at the same time durable, and yet radiating a great amountof heat.

Having thus deseribed my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The burner C, having the slits c c, and the central button 1,combined and arranged together substantially as and for the purposedescribed.

2. The screen D, having clusters of apertures d d d, as and for'thepurpose described.

3. The arrangement and combination of the burner 0, screen D, andchamberE, having the heating compartments e e e, substantially as and for thepurpose specified.
